The inventor of the application finds out through research that the reason why the user mistakenly thinks that the water heater fails is that: the temperature displayed by the display of the traditional electric water heater is approximately equal to the actual temperature of the inner container of the electric water heater, when the electric water heater is in the capacity-increasing mode, the target heating temperature of the inner container of the electric water heater is greater than the set temperature of a user, so that the actual temperature of the inner container of the electric water heater is greater than the set temperature of the user, and the temperature displayed by the display of the traditional electric water heater is also greater than the set temperature of the user, so that the user mistakenly thinks that the water heater fails.
In order to solve the problem that the actual heating temperature is greater than the set temperature of the user and the difference between the two temperatures is large, so that the user mistakenly thinks that the water heater fails, the inventor finds out through intensive research that the display logic corresponding to the capacity increasing mode needs to be designed, namely the display of the electric water heater is controlled to display the temperature T displayed by the inner containerDisplay deviceAnd a user-set temperature TIs provided withAnd T isDisplay device≤TIs provided with.
